Commit Message

Pierrick Bouvier Nov. 28, 2024, 9:37 p.m. UTC 
This boot an OP-TEE environment, and launch a nested guest VM inside it
using the Realms feature. We do it for virt and sbsa-ref platforms.

Signed-off-by: Pierrick Bouvier <pierrick.bouvier@linaro.org>

-----

v2:
- move test to its own file
- add sbsa test
- check output of `cca-workload-attestation report`
